Chemical Companies Say "Trust Us" But Violations Belie Their Rhetoric

Although 13,868 chemical manufacturing facilities are active in the U.S. today, state and federal agencies were only able to inspect 42 percent of them over the past three to five years. This map shows those inspected facilities as well as more information about each facility and the companies that own them.

A Stricter Air Quality Standard Will Improve Our Health

Chemical Hazards in Your Backyard

This map shows the locations of facilities in Illinois, Indiana, Iowa, Michigan, Minnesota, and Wisconsin that use or store at least one of nine dangerous chemicals selected from a set that they have to report to state agencies under the Emergency Planning and Community Right-to-Know Act. The map indicates whether a facility also reports to the federal EPA under the Risk Management Program.

Reducing Chemical Risks: States on the Front Line

Find out if your state has taken action to protect your family, friends, and neighbors from toxic chemicals with our map. You can also find out if policies are at risk of being overturned through preemption in proposed federal Toxic Substance Control Act legislation.

Schools Within the Vulnerability Zone of a Hazardous Chemical Facility

One in every three schoolchildren in America today attends a school within the vulnerability zone of a hazardous chemical facility. We value our children and do everything we can to keep them safe. Yet, one area that has proved surprisingly resistant to effective oversight is toxic chemicals.

High-Risk Facilities Near Schools – Nationwide

This interactive map highlights schools within one mile of high-risk chemical facilities across the country. Users can zoom in and out, search by school or city, and adjust various data levels to see which schools in their areas are inside a high-risk zone for releases, leaks, fires, and explosions.

High-Risk Facilities Near Schools and Hospitals – Louisiana

This map set pinpoints schools and hospitals within a one-mile radius of high-risk chemical facilities in the state of Louisiana and several communities in the state. Users can see which schools and hospitals in their areas are inside a high-risk zone for releases, explosions, and other incidents.

High-Risk Facilities Near Schools and Hospitals – Illinois

This interactive map and associated map set pinpoint schools and hospitals within a one-mile radius of high-risk chemical facilities in the state of Illinois and several communities in the state. Users can see which schools and hospitals in their areas are inside a high-risk zone for releases, explosions, and other incidents.

High-Risk Facilities Near Schools – New Jersey

High-Risk Facilities Near Schools and Hospitals – California

This map set pinpoints schools and hospitals within a one-mile radius of high-risk chemical facilities in the state of California and several Los Angeles-area communities. Users can see which hospitals and schools in their areas are inside a high-risk zone for releases, explosions, and other incidents.

High-Risk Facilities Near Schools and Hospitals – Texas

This interactive map pinpoints schools and hospitals within a one-mile radius of high-risk chemical facilities in the state of Texas. Users can zoom in and out of the map and click to see which hospitals and schools are inside a high-risk zone for releases, explosions, and other incidents.

Industrial Facilities Using Hydrogen Fluoride

This interactive map shows the locations of industrial facilities that use or store hydrogen fluoride, a highly toxic and extremely corrosive substance that can cause serious respiratory and other health problems. These facilities pose a serious risk to surrounding communities in the event of a catastrophic incident.

Industrial Facilities Using Chlorine Gas

This interactive map shows the locations of industrial facilities and drinking water and wastewater treatment plants that use or store chlorine gas, a highly toxic substance once used as a chemical weapon. These facilities pose a serious risk to surrounding communities, especially in the event of a leak, explosion, or other catastrophic incident.

Rail Accidents Involving Toxins

This interactive map, created after the Lawtell, Louisiana, derailment in August 2013, shows the locations of rail accidents throughout the United States that have involved toxins. Displaying data from 1991 until 2012, the map highlights derailments, rail car leaks, fires, and other incidents that have put people at risk.

Explosive Chemicals

This interactive map was created in response to the chemical plant explosion in Geismar, Louisiana, on June 13, 2013. Five chemicals were stored at the plant in large quantities –1,3-butadiene, propane, propylene, ethane, and ethylene.

There are many facilities that have at least one of the listed chemicals on-site, and many of those facilities have had at least one accident.

Anhydrous Ammonia

The fertilizer plant explosion in West, Texas, in 2013, prompted us to create this map. Two chemicals were stored at the plant in large quantities – anhydrous ammonia and ammonium nitrate.

Anhydrous ammonia is produced or stored in almost 10,000 facilities. When sprayed with water, anhydrous ammonia can produce a toxic cloud that can be lethal. It is potentially flammable and explosive when heated.

Potentially Dangerous Facilities Impacted by Hurricane Sandy

In October 2012, Hurricane Sandy smashed and flooded entire communities across several mid-Atlantic and Northeast states. The storm spilled dangerous materials into various bodies of water, potentially threatening the health of residents already dealing with the more direct damages from the disaster. Find nuclear, petroleum, and toxic-producing facilities in counties hardest hit by Sandy on this map.
